A White to Brown crystalline solid. | [Uses]
5-Propylbenzene-1,3-diol is an intermediate used to prepare Cannabigerovarin (C175140) which stimulates thermosensitive transient receptor potential (TRP) channels of vanilloid type-4 (TRPV4)-mediated [Ca2+]i with moderate-high efficacy (30-60% of the effect of ionomycin) and potency (EC50 0.9-6.4 μM), | [Definition]
ChEBI: Divarinol is a 5-alkylresorcinol in which the alkyl group is specified as propyl. It has a role as a semiochemical, a fungal metabolite, a lichen metabolite and an animal metabolite. | [Mechanism of action]
5-Propyl-1,3-benzenediol acts by inhibiting the activity of certain enzymes involved in the synthesis of fungal cell wall components, such as β-glucan and chitin, and other enzymes involved in the synthesis of viral proteins, such as reverse transcriptase and protease. | [Synthesis]
In a 100 mL round bottom flask, open to the atmosphere was added the crude product Benzene, 1,3-dimethoxy-5-propyl (0.736 g, 4.08 mmol, 1.0 equiv.) and a 1:1 mixture of glacial acetic acid (20 mL, 349.7 mmol, 17.4 M) and hydrobromic acid (48% in H2O, 20 mL, 368.3 mmol, 18.4 M). The reaction mixture was refluxed at 125 °C for 3 hours while stirring, or until the starting material was consumed via TLC analysis. At this point, the reaction was allowed to cool to room temperature and quenched by the addition of DI H2O. The biphasic solution was added to a separatory funnel, wherein the organic portion was extracted Et2O (ca. 3x 20 mL). The organic layers were then combined, neutralized with a concentrated sodium bicarbonate solution (ca. 30 mL), washed with a saturated brine solution (ca. 50 mL), dried over MgSO4, filtered, and concentrated in vacuo to afford the final product without 5-Propyl-1,3-benzenediol (0.609 g, 99% yield) as a pale yellow oil.
 | [Solubility in organics]
5-Propyl-1,3-benzenediol is soluble in N,N-dimethylformamide, soluble in methanol, slightly soluble in glacial acetic acid, very slightly soluble in chloroform, almost insoluble in water. |
